ANDY F. MILLER, O'F HENDERSON, TENNESSEE.-

To all whom it may concern:

Be it known that I, ANDY F. MILLER, a citizen of the United States, residing at Henderson, in the county of Chester and State of Tennessee, have invented a new and useful Furnace,-of which the following is a specification.

T'liis'invention relates to portable furnaces, such as are used for agricultural and domestic pull'poses.

1e object of the present invention is to simplify the construction of such furnaces, and to impart added utilit thereto, whereby the range of usefulness wiil be materially increased, and the operation rendered more certain. i v I lVith the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists, generally stated, in a furnace embodying an 'open-ended body and a circumferentially adjustable internally arran ed utensil support at one end thereof, whereby, the furnace may be readily adapted for supporting pots of different sizes.

The invention consists-further in a domestic furnace embodying a cylindrical openended body provided with suitable supporting legs and a draft door adjustable from the lower end of the body upward, whereby the combustion of the fuel may be readily controlled, and a circuinferentially adjustable internally arranged utensil support-ada ted to accommodate pots, kettles and the ike, of different sizes.

The invention consists further in thevarious novel details of constructionof a portable furnace, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification and in which like characters of reference indicate corresponding' parts, Figure 1 is a view in perspectiveof a ortable furnace constructed in accordance with the present invention. Fig. 2 is avertical longitudinal sectional view. Fig. 3 is a to lanview.

The body 1 of the furnace, which is open at both ends, may be constructed of any suitable material, metal, and may e of any desired contour in cross section, usually circular.

In one wall of the body and near the lower end thereof, is a rectangular opening? constitutin a fuel charging mouth, which is adapteto be, closed, when desired, by a slid- FURNACE.

ing door 3 that is mounted between guides 4 riveted or bolted to the body. The upper end of the door is provided with a hand old 5 by which it may be operated to open and close the same.

Arran ed within the upper ortion of the body an referably flush with its upper ed e, is a utensil sup ort 6 that is constructed 0 a band of meta of any desired width and thickness, and that is held assembled with the body by bolts 7 and nuts 8, these latter elements serving also to hold legs 9 combined with the body which are b preference constructed of flat strap meta or they may be cast or otherwise formed,

It will be noted with reference to Fig. 3 the utensil support 6 does not entirely encircle the interior of the body, but is suflioiently shorter than the circumference thereof to ermit of an extended range of adjustment t us to adapt the furnace to support pots and kettles of different sizes. In order to stay the free ends of'the utensil support, a brace bar 10 is employed, which is disposed flush with the upper ed e of the body, and secured by the bolts 7 and nuts 8 The utensil suport is provided with a. series of orifices 11 or the urpose of ermitting the adjustment referrerFto, one a 'ust-ment being indicated in Fig. 3, by whic it will be seen that in order to change the diameter of the support -it will only be necessary to remove the bolts with which a pipe may be assembled if desired. It will be seen from the foregoing description that by means of the novel form of utensil su port the furnace'will be exceedingly usofu inasmuch as it may be adapted or use in positions where ordina furnaces of this character could not be emp oyed.

What is claimed is 1. A furnace com rising a body, a circumferentially adjusts is internally arranged utensil support at the upper end, an externally disposed brace bar, .and bolts assing through'the body, support and, brace at for holding the parts assembled and in adjusted positions.

' 2. A furnace comprising a body, an inter- 2 aamaoe nelly arranged utensil support at the upper In testimony that I claim the foregoing as end thereof and provided adjacent to its termy own, I have hereto affixed my signature minals with a plurality of orifices, an exterin the presence of two witnesses.
